How do those Real Housewives of Beverly Hills remain so age defying? They have a little help from their friend Dr. Paul Nassif!

Dr. Nassif is husband to Adrienne Maloof, who has brought many of her RHOBH cast members in for a session with the good doctor.

In this Celebuzz exclusive, Dr. Nassif talks about his “Housewife mini-lift” and “Housewife facelift” — two procedures he developed to create a more natural post-surgical look. He also reveals the latest in technology when it comes to maintaining a youthful look!

One of his clients is Kyle Richards, who will once again be in the hot seat on tonight’s RHOBH reunion special. Last week, she admitted that the show is “mental torture.”

”It’s like a torture chamber and Andy Cohen is our psychotherapist,” she quipped.
